3.6 Fume ducts

The unit is a "C type" with sealed chamber and forced draught, the air inlet and fume out-
let must be connected to one of the following extraction/suction systems. The unit is ap-
proved to operate with all the Cxy and Bxy flue configurations given on the dataplate
(some configurations are given by way of example in this section). Some configurations
may be expressly limited or not permitted by law, standards or local regulations. Before
proceeding with installation, check and carefully observe the above-mentioned prescrip-
tions. Also, comply with the provisions on the positioning of wall and/or roof terminals and
the minimum distances from windows, walls, vents, etc.

This C-type unit must be installed using the inlet and fume exhaust ducts sup-
plied by the manufacturer in accordance with UNI-CIG 7129/92. Failure to use
them automatically invalidates every warranty and relieves the manufacturer of
any liability.
For fume exhaust pipes longer than 1 metre, during installation take into ac-
A
count the natural expansion of the materials when the boiler is operating.
To prevent deformations, leave an expansion space of approx. 2 ÷ 4 mm for every metre of pipe.
Connection with coaxial pipes
fig. 29 - Examples of connection with coaxial pipes (
For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions, refer to sec. 5.1. Any horizontal sections of the fume exhaust must
be kept sloping slightly towards the boiler, to prevent condensate from flowing back to-
wards the outside and causing dripping.

Before proceeding with installation, check with table 2 that the maximum permissible
length is not exceeded, bearing in mind that every coaxial bend gives rise to the reduc-
tion indicated in the table. For example, a Ø 80/125 duct comprising a 90° bend + 1 hor-
izontal metre has a total equivalent length of 1.5 metres.

Separate Ø80 ducts can be connected directly to the unit.
Before proceeding with installation, make sure the maximum permissible length has not
been exceeded, by means of a simple calculation:
1. Establish the layout of the system of split flues, including accessories and outlet ter-
minals.
2. Consult the table 4 and identify the losses in m
ponent, according to the installation position.
3. Check that the sum total of losses is less than or equal to the maximum permissible
length in table 3.

3.7 Condensate drain connection

The boiler is equipped with a trap to drain condensate. Carry out the following instruc-
tions for fitting.
1. Fix the support bracket "A" to the bottom of the boiler.
2. Connect the preformed black tube "B" to the condensate drain "S" on the bottom of
the boiler, fixing it with a clamp.
3. Remove the trap ring nut "C" and insert the preformed black tube "B" in the special
opening, making sure to fit the seal "D".
4. Refit the trap ring nut, insert it in the bracket and fix with the special clip "E".
5. Connect the flexible tube "F" from the trap to the condensate drain system.
